The Vevor ratchet chain binder set is built for securing heavy loads during transport, industrial work, and agricultural use. Made from 45# cast steel, these binders are designed for 5/16" to 3/8" chains and provide a 7,100 lb secure working load. The long anti-skid handle and ratcheting mechanism help make tightening and loosening easier with less effort. A detachable handle design allows for more convenient storage in trucks and toolboxes. This 4-piece set is suited for flatbed trailers, freight applications, and other demanding tie-down jobs.
